To all whom it may concern:

Be it known that 1, WILLIAM B. Moses, a citizen of the United States, residing at WVatertown, in the county of liliddlesex and State of Massachusetts, have invented certain new and useful improvements in Ignition Apparatus, of which the following isa full clear, and exact description.

TIllS invention relates to Ignition Apparatus and with regard to -,.certain more specific features thereof to adapter means whereby batteryignition may be provided in connection with an internal combustion engins originally designed for another type of ignition.

The invention has for one of its important objects to provide means interchangeable with original orstandard parts of the electrical system related to an internal combus tion engine whereby the storage battery of the system maybe quickly and easily adapted to supply current for the ignition of the en inc.

inother object of the invention is to provide battery ignition adapter means of Simple, inexpensive and compact character. Another object of the inventionlies in the provision of means for effecting variations in the timing of the ignition sparks-which means affords ready connection with the original or standard devices forvaryingthe timing of the spark obtained by the original tyne of ignition.

till another object of the invention comprises the idea of a substantially unitary structure comprising an attaching or adapter bracket, an igniter mechanism,

ignition coil and the actuating means for varying the timing of the sparks.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists of the various features of construction, combinations of elements and arrangements of parts exemplified by the construction hereinafter set forth and the scope of the application of which will be indicated in the following claims. 7

In the drawings wherein there is shown one of various possible embodiments of the invention, Figure 1 is a plan view of a portion of the forward end of a Ford car showing the present invention in full lines with the original or standardparts of the car dotted. The wiring is omitted for the sake of clearness. Fig. 2 is a view similarto Fig. l but partially in section and with other parts broken away to show more clearly the interior-construction. Fig. 3 is view in side elevation showing the standard parts of the engine and standard electrical equipment in dotted lines' The adapter bracket and its appurtenances are shown in full lines and the adapter bracket is sectioned to show more cl arly the interior construction, the section line being taken along he'lines of the axis of the enerator armature shaft. Fig. 4 is a view 0 Fig. 1 in front elevation, the adapter bracket being brolren away, however, substantially along the line 4-4 of Fig. 1 to show the driving connections as they are housed by the correlation of the adapter bracket, the engine and the timing gear housing cover plate.

Referring now more particularly to the drawings, there is indicated at 10 the main casting of an internal combustion engine. The engine cylinders are provided in this casting and it serves also to journal a crankshaft 11 and an intermediate or cam shaft 12 which latter is often "termed the timer shaft, At the forward end of the latter shaft and positioned forwardly of the casing casting 10 is a commutator 13 of well-known construction and which serves as a part of the standard Ford ignition apparatus.

This commutator comprises anarm 14 carrying a contact roller 15 and as the. timer casting 10 is provided with an offset portion- 20 which serves in part as a housing for the so-called timing gears 16, and 17. This housin is supplemented by a cover plate securef by means of bolts passing into a flange 22 of the housing and when so supplemented an oil tight casing is formed for the protection of the timing gears. Formerly it was the sole function of the coverplate to house the timing gears but later the cover plate was extended as indicated in Fig. 2 by the extension 23 to provide a wing or laterally extending bracket from which parts of the electrical system might be sup .ported.

The forward end of the engine casing is open to permit the projection therethrough of the timing gear 1'2. A bracket or intermediate member has been used as standard construction to lit against the engine adjacent the point of opening and this bracket member has been secured to the engine by means of loolts respectively alcove and below the projecting timing gear 17 and by means of a third bolt projecting rearwardly into the bracket member from the timing gear housing cover plate. Also according to standard construction a generator unit has heen mounted rearwardly of the bracket member secured thereto by means of bolts passed through the cover plate e);- tension, through the bracket member, and into the end cap of the generator. is an ii iportant f ature of the invention. to provide a hraclret or intermediate member corresponding to a degree w th the standardhraclretjust referred to. the preferred form of the present invention the points of attachment correspond with the points of attachment of the standard hr clret, the

present case, the bracket or intermediate ineinheris shown at 2% having pi ovision at 25, 26 and 2 for attachment by means of bolts similar to the attaching bolts previously referred "to if not oy the identical bolts.

The bracket or intermediate member 2A is 31 forming a substantially horizontal table 32 to which an ignition coil 33 of usual type may be secured. The ignition coil 33 is provided with a metal base as having diametrically opposed lugs or projections 35 by, which it may he secured to the table 32. Below the table and secured for pivotal movement by means or" a stud screw l0 there is a lever 41 having the peculiar configuration shown clearly in Fig. 1 and provided at its outermost extremity with an open-ended slot 42. Confined between the walls of the slot 42 there is a pin 4.3 extending upwardly from an operating arm M, the latter connecting through a slot in the casing of the igniter 29 with the contact set of the interrupter mechanism of the igniter. A con-- necting rod 4L5 has one end connected with the lever 41. substantially midway of the extremities of the latter as shown clearly in Fig. 1. The other end of the connecting rod is provided with a clamping device at whereby it may be secured to the standard operating rod a? which connects in turn with the contact arm 14 of the standard commie tator mechanism.

The generator of the electrical system has its armature shaft extended to terminate within the housing provided hy the associ- V re eases ation of the intermediate or bracket rnernher, the engine casing andthe timing gear housing cover plate. A small gear fixed upon the armature shaft extension meshes with the timing gear 17 forming a i nition, may obtain them at small cost with o a minimum amount of du'ncultv in tion and without the necessity or employing skilledlahor. changing over the stand.- ard system toadapt it for use withthe hattery as a source ignition, the bolt hold the loraclret or intermediate nemher to engine and the generator-and bracket to the coverplate extension are removed. The generator is laid one side a new hraclret with its appurtenances, the igniter coil connecting rod, is secured in position. The standard gear on the armaturefshait extension may then be discarded and a new cornhination of gears applied, as shown clear 3, spur gear 50 and the s gear 51, the spur gear being splined e armature shaft and a pin Z0 being passed through looth gears and the shaft.

The igniter 29 comprises a casing 86 hav 7 ing a lower portion 81 of reduced diameter forming a shoulder 82. assembling the apparatus, the reduced portion 81 ofthe casing is inserted within the split her-ed boss 28 and the latter is then tightened by means of bolt 83 to hold the casing securely in position. The upper portion 84: oi the casing is of enlarged diameter and cup shaped to receive any usual or suitable type of interrupter rmechanisni; Above the portion 84 is the distributor head 85 carrying the secondary terminals and contacts, and the vertical operating shaft'which carries the spiral gear 52 at its lower extremity extends upwardly through the casing carrying cams to actuate the interrupter mechanism and a movable contact which codperates with the contacts of the secondary terminals.

he many changes might be made in'thc above construction, and as many apparently widely different embodiments of the invention might be made without departing from the scope thereof, it is intended that all matter set forth in the foregoing description, or shown in the accompanying drawings, shall be interpreted as illustrative, and not in a limiting sense.
